Trolley type hot air circulation oven is the standard energy-saving cycle operation furnace, heat treatment workshop heating is mainly used in steel,special steel, machinery processing, chemical machinery, heavy industry,metallurgical smelting, casting, forging, flange, steel, wire drawing, environmental protection equipment, machinery enterprises, loader, diesel engine, military etc.industry use. Control: control by the contactor, SCR, solid, module, electronic digital, intelligent digital display, computer, PID, PLC, remote control, centralized control, program control, recording a park map, oblong figure more paper recorder, also be the paperless recorder records using liquid crystal.
Trolley type hot air circulating furnace is mainly used for temperature dryingfurnace structure of various parts of the furnace, trolley, heating device, controlsystem and other components. Frame trolley type hot air circulating furnace body shell welding steel, inner and outer walls are made of high quality cold-rolled steel plate production, small coefficient of deformation heating, lined withaluminum silicate refractory fiber needle punched cotton as heat insulation and insulation materials, reduce the furnace wall temperature. Trolley type hot air circulation oven door furnace shell is welded steel frame, is also made of cold-rolled steel sheet, lined with aluminum silicate refractory fiber needle punched cotton as heat insulation and heat preservation material. Trolley type and steel welding, bottom is provided with a walking wheel, flexible walking, the car can be pushed into the furnace body. Trolley type hot air circulating furnace moutharound the embedded with rubber asbestos packing, the door closed with a mouth rubber asbestos packing tightly, to ensure that no heat. The heating element adopts ribbon electric heating element is arranged in the furnace on both sides, respectively, made of 0Cr25AL5 alloy, the service life is long. In order to ensure the stability and uniformity of furnace, furnace is provided with aventilation device and ventilation system, ventilation device is arranged at the top of the furnace body, fan using 1Cr18Ni9Ti heat-resistant steel made incentrifugal fan. The wind guide system is composed of an air guiding plate andthe plate, the wind guide plate is arranged in the furnace top, a wind guiding groove. When the open fan, wind thrown out from the fan, the wind guidegrooves are uniformly blown into the furnace heating elements on both sides of the lower part of the air guide plate, after the wind blowing into the furnace chamber, and then from the air guide at the lower part of the suction fan fan, and then thrown around, so reciprocating cycle, heat will be generated by the heaterinto the furnace inside, the workpiece is heated evenly. Temperature controlsystem adopts PID zero trigger thyristor, intelligent temperature control. The other by Shanghai Dahua Instrument Factory multipoint automatic recorder to record the temperature and over temperature alarm of dual control, to ensure that the workpiece is not overheating. The mechanical transmission part adoptselectric interlock control, namely the door opened automatically cut off theventilator and the heating power. Door closed in place, the power can be switched on ventilator and heating element, prevent the misoperation failures andaccidents.
